One thing I did do today that turned out quite excellent, was to cut two grooves in the kayfun posts. No more wrapping the wire around the screw, just pull it tight half way around and the wire gets captured under the screw in the groove. These grooves should have been a factory implementation IMHO.
A few passes back and forth with a small triangle file and you are good to go. Also a good flush under running water to clean out the filings.
